An alchemical treatise on the quinta essentia attributed to Ramón Llull, printed by Johann Birckmann at Cologne in 1567 for Latin-reading physicians and adepts. The plates here are small woodcut initials — D, E and others set in square frames of white-line foliage, rosettes and sprigged stems, printed heavily on tanned paper — usable as drop caps, monograms or block ornament.
